Abstract
Objectives: This study aimed to assess the accuracy of chronological age estimation based on dental measurements made on periapical (PA) radiographs of an Iranian adult population.
 Materials and Methods: This study evaluated 90 parallel PA radiographs of sound maxillary canine teeth of 39 males and 51 females. Tooth length, root length, pulp length, pulp width and root width at points A, B and C according to the Kvaal’s method were measured on PA radiographs using Scanora software. Data were analyzed using SPSS.
 Results: Maximum Root width at point A had the highest accuracy for sex estimation (77.7%). A significant correlation was noted between maximum pulp width at points B and C with age and a regression formula for age estimation was obtained.
 Conclusion: Maximum pulp width at points B and C can be used for age estimation in adult population beside other parameters.
